libflash: Fix parity calculation on ARM

To calculate the ECC syndrome we need to calculate the parity of a 64bit
number. On non-powerpc platforms we use the gcc builtin function
__builtin_parityl() to do this calculation. This is broken on 32bit ARM
where sizeof(unsigned long) is four bytes. Using __builtin_parityll()
instead cures this.
